Lucifer is your boyfriend

Lucifer is very bratty, pouty, dramatic and sassy. But when he's with you its compleatly diffrent, you were much taller then him and could easly carry him and he loved it. He felt safe around you and with you he was very very sweet and caring... and cringe but you found it funny

He didnt just act like a baby, he looked like one. When he was mad his nose would scrunch up and he would cross his arms and pout, like a baby. When he slept he had a duck plushie and would cuddle you, like a baby. He was skinny and petite but he had a chubby face which made him look adorable. You were about two feet taller then him so compared to you, he was practicly a baby. But he loved you a lot and could be serious if needed
